My invention relates to gas supported airships, and more especially to the supportinggas and a method of changing at will the lift of such airships while travelling.

It is a well'lknown fact that airships travelling over long distances continuously become lighter -because of the fuel consumption. Therefore it is necessary for the purpose of compensating lift and weight to re- :duce the lift 'by letting out some of the carrying gas, which may become a comparatively big quantity after long distances have been covered. Of course this methodfis very expensive as the lost quantity of, gas will have to be re-inlated before a`new trip of According to my invention I am doing away with this drawback by infiating part of the airship with a gas which i'sdissolvf. able in water. Such a gas will be heavier' than hydrogen'or helium, but still-it has to be considerabl lighter than air so'- as tol cause lift for t e airship. Ammonia-for. ex-

ample is such a gas.

While travelling, as soon as it'seems suit`- able with regard to the continuously decreasing weight, part of the s'pecial gas may be dissolved in the ballast water of the ship thereby adequately lreducing the lift. )Also an arrangement may be provided for continually dissolving part of the gasso-that the consumption of fuel may befcompensated. l A"-further advantage of my invention isthat` thel special gas may be used fox-"extracting water from the exhaust of the mo- I tors driving the airship.. It is known that the exhaust gases of the motors contain such an amount of water that its weight would be suicient for the compensation of the.` fuel l: onsumption.

'By leading the special gas into the exhaust gases it will be possible to precipitate part of the water in which the gas will remain dissolved. In this way the desired wei ht compensation is further increased.

I by any circumstances it should become desirable again to increase-the lift of the 2 for 4the special .lifting gas or being dissolved in water, ac? 9 airship, for example after a landing where the ship may have taken over new loads, this may be attained` by simply warming the watery solution of the special as thus causingthe gas to se arate from t e water so that part of thev s ip may be re-inflated with this gas. Y

Having given a general description of my invention l now want to point 1t out more in detail referring to the drawing which represents an exampleembodying my inven tion.l

The ligure is a vertical longitudinal section through the middle potionof an airship. lIn the main gas space 1 a container as is provided having a hose 3 leading to t e water ballast container L situated in car 5. A; branch 6 of said hose is connected to the exhaust 7'. Leadings 3 :sol

and 6 are controlledjfby operated valves 8.

I do not 'want' to limit myself to the example described vor vshown in the drawing,

as many variations willoccur to those skilled in the art. l

What I claim is: l

1. An airship comprisingv a gas bag containing ordinary lifting gas; a gas bag containing lifting gas dissolvable in water; a receptacle containin bringingsaid secon said water.

2. An airship comprising a gas bag ycontaining ordinary lifting g'as; a gas bag containing ammonia; a rece tacle containing water; and means for bringlng said ammonia into contact with said water.

3. Method for compensating dilere'nces in' lift in an .airship which conslsts in using a gasdissolvable in water besides the ordinary "lifting gas, said first gas being used das a cordln as circumstances may require.

' 4., ethod for compensatingdi'erences in lift in an airshi which consists in using ammona besides t e ordinary liftin gas; said ammonia bein also used as a ifting gas' or ybeing disso ved in water. according as circumstances may require.
